SCREEN MOUNTING Filed March 24, 1950 Patented Dec. 23, 1930 PATENT oEFicE WILLIAM HENRY TAYLOR, OF DES MOINES, IOWA SCREEN MOUNTING Application filed March 24, 1930.` Serial No. 438,447.

The object of my invention is to provide a screen mounting of simple, durable and inexpensive construction for supporting screens on metal window frames. Y

More particularly, it is my object to provide a screen mounting of verysimple and inexpensive construction, whereby `screens may be quickly, easily and securely mounted on a metal frame in such manner that they 1o may be released from the inside but not from the outside. A l

With these and other objects in view, my

invention consists in the construction, ar-

rangement and combination of the various i5 parts of my screen mounting, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which z l Y 2o Figure l shows a front elevation of a screen mounting embodying my invention.

Figure 2 is a detail, sectional View taken onl lthe line 2-2 of Figure l, parts being broken away. l Y ,o

a Figure 3 is a vertical, sectional view taken on the line 3-3 of Figure l.

Figure l is a perspective view illustrating parts of the screen mounting; and Y Figures 5, 6 and 7 are sectional views showing modified forms Vof screen fastenings.

In themanufacturing and merchandising ofmetal Window frames, I haveexperienced, some difficulties in mounting a screen on the frame in a satisfactory manner. The great est difficulty has rbeen VAthe provision of an inside` control whereby the screencan Vbe de?V tached from the inside but not from the outside of the building.

y In the drawings herewith, I have indicated.'

generally by the lreference character l0 a A `metal window frame having at its outer pori f-tion a'peripheral rabbet 12 and outside of that anfoutwardly extending flangeV lll.l In v order tolshow the relationship ofthe parts,

V19. TheV frame 18 comprises a peripheral channelelement 2O with a slightly reduced neck indicated at 22 in Figure 2 and with short flanges 2li and 26 on opposite sides of the channel.

The edges of the screen wire are forced into the channel and a stili' wire 28 is forced througlithe narrow neck of the channel for binding the screen wire in place.

The material of the frame 18 has sufficient resiliency to permit forcing the wire or rod 28 yinto thechannel 20.

Projecting inwardly from the sides of the frame 18 outside the screen wire 2O are oppositely arranged lugs 30. Extended through each lug 30 and through the screen wire is a lbolt 32, having a head`32a, an angular shoulder B2b, forming part of its shankportion, a reduced smooth shank portion 32c and a threaded shank portion 32d.

-On the threaded shank portion 32d, is a wing nut 34C.

AFor each bolt 82, there is provided a locking bar 36 having an elongated slot 38 through which the shank ofthe bolt extends.

The width of the slot 38 is such that when l the' shoulder32b is received in the slot 138,

the locking bar 3G and bolt 82 are held against relative rotation.

. On account of the reduced size of the shank portions 320 and 32d, the bar 36is swiveled Aopposite lugs 30 whenfthe screen is set into the rabbet l2. AvIn installing the screen, the wing nutsi are loosened sufficiently to` allow the bars 36 to loosely hang downwardly. The v' screen frame 18 is then placed in the rabbet 12 as indicated in Figure 3.

Each locking bar 36 is then swung up to position shown at the left-hand side of Figure 2 and slid outwardly so that its end enters one of the slots, as illustrated at the right-hand side of Figure 2.

The wing nut is tightened preferably after the locking bars 36 have been inserted through t-he slots. This will draw the angular shoulder 32?) into the. slot 38 in each instance. lVlien that is done, the bolts 32 can not be rotated from the outside because the shoulders will not turn in the slots, and the slots are of such size that the walls thereof engage the locking bars 36.

On account of the construction of the frame 10, the pane 40 in the window sash 16 does not interfere with the bolts 32 or the wing nuts 34 (see Figures 2 and 3). Nhen it is desired to remove the screen, the sash is swung out of the way, and the wing nuts 34 are loosened to permit the locking bars 36 to be withdrawn from the slots by moving them from position illustrated at the right-hand side of Figure 2 to the position illustrated at the left-hand side thereof.

When the wing nuts are properly loosened, the bolts 32 and bars 36 are loose relative to each other and the bars can then drop down.

It is, of course, obvious that after the bars are withdrawn from the slots, the bolts can rotates also to permit the bars to drop down.

Referring to Figure 2, it will be obvious that, as the wing nuts 34 are tightened, the outer surface of the screen frame acts (as indicated at 35) as a pivot for the lock bar 36.

In Figure 5, I have illustrated a slightly modified form of lock bar 36, one end of which coacts with the lug 30 (as indicated at 35) for drawing the screen frame 2Q inwardly toward the window frame 14,Vwhen the Wingnut 34 is tightened. It will be noted that the locking bar as well'as'the wing nut is controlled from the inside of the building in this type of scieeii mounting. j

Figure 6 illustrates a slightly ditierent form of fastener. 1he frame 10 is, as above described, with the rabbet 12 and flange 14. The screen frame 18 is as already described, but it has the lug 40 outside the screen wire 19, provided with a threaded hole 42. The locking bar 36 is as above described. A screw bolt- 44 extends through the slot 38 of the loci@ ing bar and is screwed into the vlug 40.

In Figure 7 is shown a slightly modiiied form of screen frame 46, of tubular form having the wire 19a secured thereto. The frame 46 has a lug 48 projecting from it on the inside of the wire 19a. The lug has a threaded hole 49. The locking bar 50 is preferably straight and has the elongated slot 51 to receive a similar screw bolt 52, and forced through the wire 19a and threaded into the hole 49.

There is thus provided a simple and inexpensive structure for accomplishing the purposes hereinbefore set forth with the parts so arranged that the, wing nuts which release the screen are located on the inside of the SCleeIl.

Changes may be made in the details of the construction and arrangement of the various parts of my improved screen mounting without departing from the essential purposes and features of my invention, and it is my intention to cover by my claims any modified forms of structure which may be reasonably included within the scope of such claims.

I clailn as my invention:

l. In a window screen mounting, the coinbination of a frame having a screen therein with lugs projecting inwardly from the frame, bolts loosely mounted in said lugs having heads and angular shoulders adjacent to said heads and having threaded por tions on the opposite side of the frame from said heads, nuts on said bolts, locking bars mounted on said bolts having elongated slots receiving the bolts, said slots being of such width that the angular shoulders can not turn in the slots.

2. In a structure of the class described, the combination of a screen frame and screen therein with lugs projecting inwardly from the frame on one side of the screen, locking elements slidably and rotatably mounted in said lugs, adjustable securing members mounted on said elements on the opposite side of said screen, and locking bars slidably but non-rotatably supported on said elements.

3. In a structure of the class described, a screen frame having inwardly projecting lugs, members slidably and rotatably mounted in said lugs, locking bars mounted on said members, said members and locking bars having coacting parts for permitting sliding movement of the locking bars on the members and preventing relative rotarv movement of the locking bars, and means on said members on the opposite side of the lugs from said locking bars for drawing the locking bars toward the lugs. 4

4. For use with a window frame having locking lug openings, a screen frame having perforated lugs, clamping bolts extending through said lugs, and locking lugs on said clamping bolts and adapted to coact with said locking lug openings.

5. For use with a window frame having locking ylug openings, a screen frame having perforated lugs, clamping bolts extendin T through said lugs, locking lugs on said clamping bolts adapted to coact with said locking lug openings, and means on said screen frame for said locking lugs to bear against to serve as pivots for the lockin lugsiwhen the'clamping bolts are tightenedg.

6. The combination of a window frame having a peripheral rabbet formed with locking lug openings, a screen frame having lugs, locking bars adapted to be projected into said openings, and means for fastening the lugs to the bars. Y Y

7. The combination of a Window frame having a peripheral rabbet formed With locking lug openings, a screen frame having lugs, locking bars adapted to be projected into said openings, and means for fastening the lugs to the bars, said means being adjustable for drawing the bars againstI the screen frame and pressing the screen frame against the Window frame.
